Only one month after the War Against Giygas, Ness and his friends must face an unexpected evil from the realm of the Deep Darkness. Who could be behind the war between the Tenda and the Jungle Monkies?

The world is at peace. Giygas, the universal destroyer has been vanquished, and all is good in the world. Celebrations were held for the Four, and each was met with personal successes. The Four went their seperate ways as they entered adulthood. They left home to search for a place of their own. The past is but a faint memory now...

In an attempt to salvage proper history, Ness travels back in time and ends up leaving a horrifying mark on the future of Eagleland. Can he and Jeff correct Ness' considerable mistake by going even farther back in time?

For years, the Mr. Saturn and the Starmen have engaged in war. After Ness' defeat of both Giygas and Starman DX, all was quiet on the battlefront: until now. New information may reveal that the Starmen are, in fact, alive and well... and ready for war.
